ADI ADAQ7980 16位ADC μModule 数据采集系统方案

ADI公司的ADAQ7980/ADAQ7988是16位模数转换器(ADC) μModule® 数据采集系统,集成了四个常见信号处理和调理模块,采用支持各种应用的系统级封装(SiP)设计.内置一个高精度低功耗16位SAR ADC,一个低功耗高带宽高输入阻抗ADC驱动器,一个稳定的低功耗基准电压缓冲器和一个高效的电源管理模块,可简化数据采集系统的设计过程.主要用在自动测试设备(ATE),电池供电仪器仪表,通信,数据采集,过程控制和医疗仪器.本文介绍了ADAQ7980主要特性,框图,以及评估板EVAL-ADAQ7980SDZ主要特性,简化框图,电路图,材料清单和PCB设计图.

The ADAQ7980/ADAQ7988 are 16-bit analog-to-digital converter (ADC) μModule® data acquisition systems that integrate four common signal processing and conditioning blocks into a system in package (SiP) design that supports a variety of applications. These devices contain the most critical passive components, eliminating many of the design challenges associated with traditional signal chains that use successive approximation register (SAR) ADCs. These passive components are crucial to achieving the specified device performance.

The ADAQ7980/ADAQ7988 contain a high accuracy, low power, 16-bit SAR ADC, a low power, high bandwidth, high input impedance ADC driver, a low power, stable reference buffer, and an efficient power management block. Housed within a tiny, 5 mm × 4 mm LGA package, these products simplify the design process for data acquisition systems. The level of system
